Abstract
Nafion-H catalyzes the Mukaiyama aldol condensation between aromatic aldehy des and the Danishefsky diene whereas the corresponding imines directly und ergo hetero Diels-Alder cyclization to form 2,3-dihydro-gamma -pyridones. S ome chiral acetal derived aldehydes were round to undergo Mukaiyama aldol c ondensation in the presence of Lewis acids but not with Nafion-H. (C) 2001 Elsevier Science Ltd. All rights reserved.
